안녕하세요 index.js 파일이 문제 인것 같은데 ~ import React from ' react '; import ReactDOM from ' react-dom '; import ' ./index.css '; import App from ' ./App '; //import * as serviceWorker from './serviceWorker'; import reportWebVitals from ' ./reportWebVitals '; import { Provider } from ' react-redux '; import ' antd/dist/antd.css '; import { applyMiddleware , createStore } from ' redux '; import promiseMiddleware from ' redux-promise '; import ReduxThunk from ' redux-thunk '; import Reducer from ' ./_reducers '; const createStoreWithMiddleware = applyMiddleware (promiseMiddleware , ReduxThunk)(createStore) ReactDOM . render ( < Provider store = { createStoreWithMiddleware (Reducer , window . __REDUX_DEVTOOLS_EXTENSION__ && window . __REDUX_DEVTOOLS_EXTENSION__ () ) } > < App /> , document . getElementById ( ' root ' ) ) ; // If you want to start measuring performance in your app, pass a function // to log results (for example: reportWebVitals(console.log)) // or send to an analytics endpoint.
